FIRE-BOX FOR FORGING.

SPECIFIGATION.forming part of Letters Patent No. 506,576, dated. October10, 1893. Application filed April 13, 1893. Serial No. 470,181. (Nomodel.)

To all whom it may concern.-

Be it known that I, JAMES T. ACE, a citizen of the United States,residing at Wilkes-Barre, 1n the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inFire-Boxes for Forging; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in fire-boxes for forging, and theobjects of my lmprovements are to provide a box which dispenses withbrick and other linings; which is durable and simple in construction;which is adapted to burn either hard or soft coal; and which may beeasily and quickly cleaned.

To this end my invention consists in the novelconstruction andcombination of the several parts as will be hereinafter more fully setforth and then pointed out in the claims, reference being had to theaccompanying drawings and the letters and figures of reference markedthereon, in which- Figure 1 is a plan viewof the fire box. Fig. 2 isasectional view taken on the lines 2 -2 of Figs. 1 and 4. Fig. 3 is aplan view of the fire-box with the crescent-like pieces and thesupplemental grate removed. Fig. 4. is a transverse vertical sectionwith the supplemental grate removed and a modified form of rocking grateshown, the said view taken on the lines 1-at of Figs. 2 and 3. Fig. 5 isa fragmentary section of a modified form of the fire-box. Fig. 6 is aplan view of the form of rocking grate shown in Fig. 4.

In the drawings A is the fire-box comprising the fuel-chamber 10 and theair-chamber 11. The fuel-chamber 10 is preferably elliptical in crosssection which admits of a greater length and less width to the fire andis provided at its upper extremity with the rectangular flange 12, thesaid flange having the groove 13 extending in line with the major axisof the elliptical fuel chamber. This groove 13 admits of placing the barofiron to be heated into the fire to a greater degree than would be thecase should the surface of the flange be perfectly flat, thus causingthe iron to be more quickly and thoroughly heated. Within thefuel-chamber and somewhat above the point where said chamber joins theairchamber are the lugs or projections 14 upon which is adapted to restthe removable supplemental grate or plate 15, the said plate having theapertures 16 for the egress of the ashes that would otherwise collectthereon. Below the fuel-chamber and formed integrally with said chamberis the air-chamber 11. At a point near the top and journaled in theeasing of the air-chamber is a rocking grate 17, the said grateconforming to the shape of the air-chamber and provided with apertures18 for the egress of ashes. The rocking grate is further provided withthe handle 19 which serves as a means for rocking as well as a journalfor the grate. At the extreme lower portion of the air-chamber 11 asliding plate or valve 20 is provided, the said plate having bevelededges to fit into like grooves in the casing of the air-chamber. Thisremovable sliding plate or valve when opened will allow the ashes orother collections to descend into any receptacle placed under the platefor that purpose. The plate or valve 20 when closed directs the air,that enters the tuyere opening 21, in an upward course through the fuel.The tuyere opening 21 is located below the rocking grate 17 and abovethe sliding valve or grate 20, the said opening being connected directto the blast-pipe of a blast-engine or bellows. The flange 12 has uponits upper surface and located at the sides of the opening of thefuelchamber the crescent-like pieces 22. These crescent-like pieces arepreferably V-shaped in cross section and are removably connected to theflange 12 by the lugs or pins 23 fitting into the apertures 24. of saidflange. The crescent-like pieces 22 prevent a lateral displacement ofthe fuel when a piece of metal is inserted therein. Depending from theflange 12 are the L-shaped projections or lugs 25, the said lugs adaptedto receive the ends of legs for the further support of the firebox.

When hard coal or fuel is used the fuelchamber need not have the depthrequired for soft coal. For this purpose the supplemental grate issupplied, while the supplemental grate is removed and the rocking grateused when burning soft coal or fuel.

I wish it distinctly understood that I do not confine myself to theexact form or construe what I claim as new, and desire to secure byLetters Patent, is-- l. A fire-box having a fuel-chamber and anair-chamber, a rocking-grate held in said airchamber, and a removablesupplemental grate in the fuel chamber, substantially as described.

2. The combination,with a fire-box provided with a grate for supportingthe fuel, of crescent-like pieces on said fire-box to prevent thelateral displacement of the fire or fuel, substantially as described.

3. A fire-box having an air-chamber and a fuel-chamber, and a flangeupon the fire-box having crescent-like V-shaped pieces removablyconnected thereto to prevent the lateral displacement of the fire orfuel, substantially as described.

4. The combination with a fire-box having a fuel-chamber an air chamberand a flange upon the fuel-chamber, of a groove in said flange andextending into the fuel-chamber the said air-chamber having a rockinggrate held therein and a removable supplemental grate arranged withinthe fuel-chamber, substantially as described.

5. The combination with a fire-box having a fuel-chamber an air-chamberand a flange upon the f uel-chamber, of crescen t-like pieces arrangedupon the flange and to the side of the fuel-chamber, the air chamberhaving a grate held therein, and a removable supplemental grate locatedin the fuel-chamber, substantially as described.

6. The combination with a fire-box, having a fuel-chamber anair-chamber, and a flange upon the fuel-chamber, of a groove in saidflange and extending into the fuel-chamber and crescent-like piecesarranged upon said flange, substantially as described.

7. A fire-box having a fuel-chamber an airchamber and crescent-likepieces arrangedabove and to the side of said fuel-chamber, an aperturefor the ingress of air in the air-chainber, a sliding plate or valveheld removably in the air-chamber below the air inlet to direct the airin an upward course and as a support for the ashes, and a grate forsupporting the fuel, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
